Gas Boiler, Pilot Not Staying On

[macher]

Hi we have a gas boiler and have no heat. Tried to light the pilot but it doesn’t stay on. It ‘clicks’ off after a minute or 2. I noticed that there’s no pressure. I believe water has to be fed in the system?

Would having no pressure and water needed to fed be the cause of the pilot not staying on? Thanks!

Had the same issue with gas hot air. The gas valve was bad.
